Patented Mar. 22, 1932 UNITED STATES PATENT: oFFIcE ZACHARIAROUTTENBERG, on LOS ANGELES', CALIFORNIA SEWING MACHINE PRESSER FOOTATTACHMENT Application filed January 20, 193(1. Serial No.1'422,048.

I provide an attachment which can easily he slipped over the end of apresser-foot and being designed to guide the edge of one material in acertain relation to another material.

Another object is to provide an attachment 1 made of a single piece ofmaterial bent to snugly fit around the end of a presser-foot and havinga rolled-in edge to be on the underside of the presser-foot when theattachment is in operative position.

Other objects will appear from the following description and appendedclaim as well as from the accompanying drawings, in which- Fig. 1 is aside elevation of a simple presserfoot of a sewing machine of which theunderside of the front end is set off or back so that the underside ofan attachment comes flush P with the remaining portion of the foot, anattachment being indicated in section on line 11 of Fig. 2. a

Fig. 2 is a top plan view of the attachment in proper position on thefront end of a presser-foot of which only a portion is indicated in thisillustration.

Fig. 3 is a cross section on line 83 of the attachment illustrated inFigs. 1 and 2, a narrow strip of material being also indicated in properrelation to the attachment and above and in a certain relation toanother piece of material.

In the use of a sewing machine two or more pieces of difierent materialsare frequently stitched together and preferably in a straight or evenlyappearing manner, as, for instance, by a parallel stitching near one ofthe edges of a narrow strip of material to fasten this strip to anotherpiece of material, as roughly posed under the presser-foot 5 and withone edge guided by and within the rolled-in endv 6 of the attachment 7.

The resser-foot 5 is always in a certain relation to a needle in anysewing machine,

, larger or remaining portion of indicated in Fig. 3, where the strip 4is disferred to and explained above.

in the illustration of Fig. 3, a portion of a needle being indicated at8.

By this arrangement, if the strip 4 is tobe stitched to another piece ofmaterial 9, the ordinary operation of the needle 8 will result in astitching evenly along the edge of the strip 4 at about the pointindicated at 10 whereby the strip 4: is secured to the material 9.

In the preferred form in which the attach- 60 ment is illustrated in thedrawing it is made of a single piece of material bent to firmly engagearound the presser-foot. Beginning with the rolled-in end 6, the bend at11 serves to align the attachment against the edge 12 of thepresser-foot 5, the attachment extending thence over the underside ofthe presser-foot, being again bent at 13 to align the attachment againstthe edge 14: of the presser-foot, and another bend at 15 brings theupper portion 16 of the attachment over the top side of the resser-foot.I

The attachment is, ofcourse, made of thin material and preferablyspring-like to assure a clinching of the attachmentto the presserfoot,the comparatively heavy showing in the drawings being merely used tofacilitate an illustration in section.

Though thin material would not materially interfere with the propersewing operations even in the portion of the attachment below thepresser-foot, the presser-foot in its front end is reduced or cut downasindicated at 17 in Fig. 1 so that the underside of the attachmentbecomes flush with the underside of the the presserfoot. V 7 At the sametime this off-setting of the presser-foot forms a shoulder 18 againstwhich the attachment abuts, adding to the aligning facilities of theattachment on the presser-foot besides the aligning along the oppositeside edges of the presser-foot, re-

Inasmuch as material is generally pushed or moved in the direction ofthe arrow 19.

Having thus described my invention, I claim:

A sewing machine attachment comprising a unitary member of susbtantiallyU-sliaped cross section adapted to slip endvvise over the front-end of apresser-foot, the free end of the lower shank of the U-shaped memberbeing rolled in and being also bent upwardly before this rolled-in end,providing a material edge guiding channel and a shoulder for precludinglateral displacement of the member relative to the presser foot.

In testimony that l claim the foregoing as my invention I have signed myname.

ZACHARIA ROUTTENBERG.
